发明名称 Method of forming an upholstered foam plastic seat cushion
摘要 A method for making upholstered articles comprising a foam core, an integrally attached cover assembly, and an integrally attached scrim is provided. The method includes the step of positioning an air-impermeable cover assembly over a mold cavity of a molding apparatus, applying a vacuum to the fabric through a plurality of apertures in the walls defining the mold cavity to cause the fabric to conform to the shape of the mold cavity, depositing a foam precursor into the mold cavity, positioning an air-impermeable scrim over the foam, and allowing the foam precursor to expand to form the article. The method allows upholstered articles having an integrally attached cover assembly to be manufactured using a pour-in-place process which does not utilize abherents, while still preventing bonding of the foam core to the lid and/or other surfaces of the molding apparatus.
